Fan Keqin said "um", lowered his volume, and said: "You are right, since the other party has opened this accounting training class, it is impossible not to recruit students, so there must be some students who really want to learn accounting, and there may not be problems." This requires us to identify them one by one. ”

When returning to the intelligence department, Fan Keqin found Ma Chaoqun again, instructed the other party, and transferred another team of people to monitor the Daqi accounting training class, and asked Hua Zhang to replace Shi Hui tomorrow. He's busy on this side, and he has all the people in place. On the other hand, there are people who are not idle.

Li Yanchun ate from the restaurant of the Li family's old shop, he deliberately ate for a long time, and then used the time to look up every time he ate, and used his spare eyes to look at the situation on the street outside...... This is one of his vigilant hearts.

When he finished eating, paid out, and went straight to going around in circles. That's right, it's just going around the street, as if you were shopping on the street. When you see a store, you go in and have a look, and when you see a mall, you go in. It's like a foreigner who has just arrived in the local area and maintains a curious heart, and everything feels fresh to see.

Li Yanchun did not suddenly turn back halfway on the way, nor did he suddenly pass through the back door of a certain store, so he walked normally and walked down the street. He has a patience far beyond the average person, and he also knows that sometimes, when you make this kind of action, it will make others determine your true identity. And Li Yanchun's method is to use the stupidest, the longest time-consuming, but also the most concealed self-protection mechanism. He was using his patience far beyond ordinary people to observe the situation behind him.

In this way, after three hours of wandering, the agents who were far away would report back every half hour. After Lao Qi heard the other party's actions, in the first hour, he immediately and decisively ordered to use only the street-style tracking method, with the other party's people directly behind him, and the subordinates were swapped with each other. and told them that as long as they had met with each other, they would withdraw immediately. I will send someone to replace him.

I have to say that Lao Qi's reaction made an extremely correct decision. Because once a person has the heart to observe behind him, although he does not need to suddenly turn back to observe whether there is a tail behind him, Li Yanchun's patient shopping on the street is a very clever method. Because now that you're not being followed, you're going to have to use all sorts of opportunities to observe, such as the glass in the store, or the houses on either side, or the mirror, the corner of your eye when you turn a corner, or the side of your head when you're shopping and talking to someone, which can be an opportunity for you to look behind you. And this kind of opportunity only uses the most normal behavior to observe behind you, which can be the most hidden and the least easy for people to find.

Although this method is very inefficient, it adds up to a lot, which is the fundamental reason why Li Yanchun spends so much time shopping. And this method, Fan Keqin has talked about. Naturally, it is also in the secret service textbook of the Security Bureau. Lao Qi was already experienced, and he was originally specialized in dirty work, and he was willing to learn. Otherwise, this time it might really be Li Yanchun's way. Because the longer it goes on, the more your concentration will inevitably slip. Anyone is like this, but Li Yanchun is walking in front, in his case, that is, turning passive into active, as long as there are people behind him, if you use your strongest ability for a long time, that is, patience to observe, you may not have flaws in an hour, but what about two hours? What about three hours? You promise you're not showing any signs when you're tracking?

And Li Yanchun walked from morning to evening, for more than nine hours, to determine the situation behind him. Lao Qi also changed the tail behind him almost every hour, so that in the afternoon, let the two groups of Xiong Bashan's people come to support, which was a high probability, and nothing was discovered by the other party. And it's just a high probability, and it's still not guaranteed! This shows how annoying this rally-like anti-tracking method is.

But after changing a large number of people, Li Yanchun didn't make any joint movements, but returned directly to the Wuhu Hotel, and in the restaurant of the Wuhu Hotel, after having dinner directly, he went back to the room to rest.

Seeing this situation, Lao Qi had no choice but to make a detailed report to Fan Keqin about what happened today. Fan Keqin threw him a cigarette and said, "After returning to the hotel, there is no movement in the room?" ”

Lao Qi said: "Before the humble post came, I asked the brothers who were monitoring 409, and they said that they heard the sound of him drinking water, the sound of lighting a fire with a match, the sound of Suo Suo undressing, and the sound of washing, but there was no suspicious sound coming. ”

"Hmm." Fan Keqin praised: "Your reaction today is good. If it were followed by the same brothers, it would almost certainly be discovered. ”

Lao Qi nodded and said, "This kid...... Despicability feels very cunning. ”

Fan Keqin smiled: "Yes, it's very cunning, you look at it, maybe tomorrow, it will make the brothers work for nothing." ”

Lao Qi said: "The lowly will be ready, tomorrow I will ask Ji Ran and their three groups to come over to support." Then he took a puff of cigarette, and then said, "Isn't this kid in a hurry?" Why didn't he connect, if he did, we could just take it down. ”

Fan Keqin said: "Yes, the joint is fine, and you can take him down." And every time before the joint, it must be the most cautious and cautious time for Japanese spies. Now this guy named Li Yanchun has shown far more patience than ordinary people, and he does not look eager at all, which can prove that he is going to prepare for the joint. So you have to be more patient than he is. Wait and see, in these two days, he will definitely connect. ”

Lao Qi listened, thought for a while, and said: "The joint is for sure, I'm just a little worried that the brothers below will lose their vigilance." ”

Fan Keqin said: "It's okay, you can tell the brothers repeatedly, if someone really exposes their traces...... I don't think he will be able to evacuate as soon as possible, he will try his best to pass the news back, or just fight to the death. In short, the initiative does not belong to him from the moment we know that he exists. ”

After listening to it, Lao Qi also felt that it made sense, if Li Yanchun found out that he had a tail behind him, then his first choice was definitely not to get rid of it, but to follow his plan and go shopping on the street. Otherwise, as long as you choose to get rid of it, as soon as you do it, the people behind you will definitely be able to notice it.
